BY MW AfromwE WITNESSES STATES PATENT OFFICE.

To all whom it ma/y concem:

Be it known that I, O'r'ro SELG, a citizen of the United States, resi at New York'cit Manhattan, county and tate of New Yor have invented new and-useful Improvements in Fans, of which the following is a specification.

This invention relates to -'a fan provided with novel means for efiectively the air blast over an extended area.

In the accompanying drawing: Figure 1 is a side elevation, artly in section, of my im-- proved fan, and ig. 2 a front elevation of the deflector. e s In casing '10 of an electric fan is journaled the shaft 11 of the wind vanes 12, as usual. The blast is difiused by a frusto-conical deflector 13, so secured by frame 14 to casing 10, that the base of the deflector faces the casing. 20 Deflector 13 is provided with a series of outwardly and forwardly extending in egral blades 15 arranged in rows concentrically around acentral or axialopening'lfi, These blades are formed by cutting substantially U-sha d incisions into the body .of deflector 13 an then bendin outwards, the sections which. have thus ecome rtly severed. In this way an air passage 171s formed in advance ofyeach blade 15, the several air. pasao sages being also arranged in concentric rows.

These rows are separated by a'series ot q d V I specification or Lette'ra mm,

rings or annular webs 13, set back of each other and increasing in diameter from front to' rear, while the air 'passages of the same row are separatedby conver%ng webs "or ribs 119; The rim 20 of the de e backward to form a continuous annular trough. I I It will be seen that by the means described a central air blast is forced through 0P6D|D% 4,

ctor is curved 16. This blast. is surrounded by a series 0 laterall I deflected annular blasts passing back 0 one another through the opemngsl? and ided by blades 15, thus insuring a wide distribution-of' the wind. The area of this 5 distribution" is further increased by the trough-shaped rim 20, which deflects, the outermostportion of the blast.

I claim:

Alfan rovided with a coned deflector com posed "0' a series; of flaring rings set back 0 each; other and-increasing in iameter from front to rear, a series of integral convergin ribs, and blades that extend outwardly an om the rings intermediate the ribssubstantiallyasspecified.'
